18QHTF21-13.396875-PD

Overview

The 18QHTF21-13.396875-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 13.396875 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode capability to reduce power consumption during idle periods
• Utilizes a surface-mount 4-SMD no-lead package for automated assembly

Applications

• Digital clock signal generation in consumer electronics
• Timing reference for microcontroller systems
• Synchronization circuits in communication modules

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability.

Selection Notes

Select this component when a precise 13.396875 MHz timing source is required for low-voltage digital applications. The choice depends on the necessity for LVCMOS outputs and the availability of a 1.8V power rail. Consider the physical constraints of the 2.0x1.6mm package size relative to the available board space.

Part Context

This part belongs to the Mercury 18QHTF21 series of surface-mount oscillators. The series typically offers various frequencies within the same form factor. The suffix PD indicates the inclusion of a power-down feature, distinguishing it from standard continuous-operation variants within the product line.

Replacement Considerations

Direct substitutes must match the 13.396875 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify thermal characteristics and pinout compatibility if considering alternative manufacturers. Cross-reference with other Mercury models sharing the 18QHTF21 prefix for potential functional equivalents.
